Definitions

  • This invention relates to clamping devices ,for pipe and the clamping mechanism has been especially designed for use in con-nection with evices used in the oil fields for drilling wells.
  • elevators for casings, sucker rods and the like, spiders for the casing and those devices are commonly known as clamps. All-employ some form of jaw for gripping the pipe or sucker rod and in this respect there is an analogy between all three, but the construction of the-supporting means or frame for the jaws in the elevator, the spider and the ordinaryv clamp diflers.
  • FIG. 1 is a perspective view of a spider embodying my invention with the jaws in open position.
  • Fig. 2 1s a vertical sectional view through the spider showing the jaws in clamping position.
  • Fig. 3 is a perspective view of a spider viewed from the side opposite to that shown in Fig. 1.
  • Fig. 4 is a plan view of the spider, and F ig. 5 is a fragmentary sectional view through one of the slips.
  • the base frame 1 is shown as substan-' tially rectangular with a slot 2 in one wall be inspected or re aired and .by means of which the frame can be moved into and out of position with respect to the pipe 3.
  • the sidewall '4 of the frame 1 is provided with a recess 5 to provide clearance for the toggle levers which operate-the aw member.
  • Theframe 1 carries two'sets 6 and 7 of upstanding bearing lugs, one set at each.
  • the lugs constitute bearings for the rock shafts 8 and 9 which support the rocker arms 10, 11, 12 and 13 rigidly fastened to the rock shafts by set screws 14.
  • the purpose of providing the set screws so that the rocker arms will be fast to the rock shafts is and '16 provided with trunnions 17 and 18 mounted in the inner ends of the rocker arms.
  • the jaw members 15.and1 6 are pivoted in the rocker arm's below their transverse centers only so that the upper ends of-the jaw.
  • Theslips 21 and 22 are shown as provided with transform of segments. They are removably fastened to the jaw members'i15 and 16' by bolts 24am]- 25, -The slips are removable for two purposes, first so that the sli s can cause slips having aces-cuton diflierntarcs can be introduced in the same jaws fbntaking care of various sizes-ofpipe..'
  • the main purpose of insetting I the teeth 37 with respect to the teeth 19 is as comprising a lever 38 that, when the jaws take hold of the pipe, the teeth 37 will sink intJo the pipe just enough in excess of the teeth 19 to hold the against turnin when a wrench is applied to the next'lughest pipe section. If both sets of teeth were coincident at their outer edges and a wrench was used to turn the next highest pi e section, the teeth 37 would tend to 1111 ofi or at least fail to hold as efiicientl y as with the arrangement described.
  • the jaw opening mechanism is illustrated pivoted to a lug 39 on the frame 1, the lug 39 having a stop projection 39' for the lever 38.
  • Movable longitudinally in the uide lugs 40 and 40 on the lever 38 is a og 42 which is nor mally urged into engagement with a recess 41 in lug 39 by an expansion spring 42', one end of which bears against lug 40 and the other against the pin 44.
  • the dog can be moved out of engagement with any one of the openings 41 by a hand lever 45 pivoted to the lever 38 at 45 and connected to the dog by a link v46.
  • the lever 38 is fast to a rocking stub shaft 47 in the lug 39, the inner end of the rocking stub shaft carrying an arm .48 which is pivoted to the two toggle levers 50 and 51- in eagues turn connected to the trunnions of the jaw members 15 and 16.
  • the inner ends of these levers may be received in the recess 5 when the jaws are in clamping position, the recess 5 being merely a clearance for the ends of the levers. It will be impossible to operate the lever 38 in such a manner that the pivotal connection 52 will be above a horizontal plane passin through the trunnions, because before t at can occur, the lug 40 will contact with the stop 39".
  • each side of the casting is braced by a tie rod or brace rod 54 connected to the rock shafts 8 and 9.
  • the ends of the frame 1 are provided with outstanding projections 55 and 56 which carry links 57 and 58 whereby the frame may be connectedto a hoist to move it into and out of functional position.
  • the frame maybe clamped to its support, for examplefto the casing head 62. Then the pipe is lowered by theelevator 'to the desired depth, the spread jaws are adapted to seat themselves against the pipe and swing down to seating position to hold the pipe while a new section of pipe or casing is screwed on as is Well understood, then the lever 38 will be operated to spread the jaws apart so that the pipe may be lowered a sufficient distance to allow a new section of pipe to be screwed on and so on until the desired length of string of pipe is provided.
  • the position of the pivot point 52 is important because I have found that by pivoting the toggle lovers 50 and 51 and the arm 48 at a point coinciding with the plane passing through the axis of the opening in the frame that the jaws can be opened with relatively little
  • the frame is also the frame is provided February 27,
  • the bolts they can slips is that the bolts pass are below the longitudinal center the center of the frame.
  • the bar 54 When it is desired to remove the spider the bar 54 may be removed, then the spider can be slipped to one sidebecause the slot 2 is wide enough to permit the largest sized pipe to pass through it.
  • the nuts 24: and 25 can be reon the threaded ends e loosened as the salt water does not affect the outside nuts. Even if it should the nutsare more accessible than the inner ends of the bolts. 7
  • the location of the lever 38 with the arm 48 for operating the jaws is an important part of this invention, because the aws 15 and 16 are quite heavy so that the leverage ratio must be considerable tospread them apart Therefore by locating ,the pivot point of the lever 38 between the shafts 8 and 9, the necessary leverage can be'obtained for opening the jaws.
  • slips and 22 are removable.
  • a set of sli s cani-hp' made to be used in a single set 0 jaws for varying diameters of pipe.
  • sist of a number of pairs of slips all the pairs having the same are or curve oil-their outer faces but the inner faces of each pair will differ as to are or curve, the are being that which will best suffice' for a articular diameter of pipe.
